Abstract

PURPOSE:To freely control the movement of a hull by forming an annular body by setting the opposed sides among a plurality of square-shaped superconductive coils 1 and arranging said annular body in a hull and arranging at least a pair of electrodes, setting contiguous to the opposed side, in the water on the outer periphery of the hull. CONSTITUTION:A triangular annular body is arranged in a hull, in the state where the opposed sides of square-shaped superconductive coils 1-3 are set contiguous. Electrodes 1A and 11A are arranged in water so as to be opposed to one opposed side 1a of the superconductive coil is through the wall of the hull. Other superconductive coils 2 and 3 are constituted similarly. When electric current flows in each superconductive coil 1-3, the coil magnetic field N is generated in the outward direction perpendicular to the coil surface, and the magnetic field between the contiguous coils is generated in the inward direction S. Therefore, the water stream in the direction perpendicular to the paper surface is generated in the sea water between the electrodes 1A and 1B and the electrodes 11A and 11B, according to the Feming's law. Therefore, the direction of the water stream can be changed in various directions according to the existence of application to each electrode and by the selection of the electrodes.

Description

[Detailed description of the invention] [Industry” second field of use]

The present invention relates to an electromagnetically propelled ship using superconducting coils.

[Conventional technology]

Conventional electromagnetic propulsion ships have one or a pair of superconducting coils installed inside the ship, a pair of electrodes in the strong magnetic field in the seawater created by the superconducting coils, and seawater flowing between the electrodes. When a current is passed through it, seawater is ejected by electromagnetic force based on Fleming's left-hand rule, creating Gen 1 water current? As explained above, in the conventional technology, one or a pair of superconducting coils are used, so a strong leakage magnetic flux reaches a considerable distance around the coil, and the electromagnetic propulsion ship attracts surrounding iron-based materials. ■Conversely, it is attracted to surrounding iron structures. ■Disturbs the earth's magnetic field, making it easy for ships to be detected■This creates problems. The problem in item (■) is fatal if the electromagnetic propulsion ship is for military use, especially if it is a submarine. An object of the present invention is to solve the above-mentioned problems of the conventional technology, and to provide an electromagnetic propulsion ship in which the magnetic flux of superconductivity = 1 il is less likely to leak out to the outside.

[Means to solve the problem]

In order to solve this problem, in the electromagnetic propulsion vessel according to the present invention, a plurality of rectangular superconducting coils form one annular body with their opposing sides adjacent to each other, and this One or more annular bodies are arranged in parallel within the ship's body with their respective axes substantially aligned, and one or more pairs of electrodes are respectively proximate to the opposite sides of the superconducting coil, and the outer periphery of the 90 bodies to be submerged in water. The superconducting coil is disposed in water, and is propelled by the action of the direct current flowing between the electrodes through the water and the magnetic flux of the superconducting coils.

[For use]

A plurality of rectangular superconducting coils are arranged with opposite sides of each coil next to each other to form two annular bodies, and each axis of the two annular bodies is approximately bent. Since they are installed side by side inside the hull, the lines of magnetic force generated between the adjacent sides of the superconducting coils cancel each other out, suppressing the range of leakage magnetic flux.

【Example】

Embodiments of the electromagnetic propulsion vessel according to the present invention will be described below with reference to six drawings. FIG. 1 is a side view of this embodiment. In FIG. 1, 1.
2.3 are rectangular superconducting coils, LA and IIA, respectively.
are representative electrodes corresponding to the superconducting Koi Katagawa, 5
Hai! i A cylindrical body made of magnetic material, 10 the hull, 20 a power supply for supplying power to the superconducting coil and electrodes, 30 a switch having the function of determining the magnitude of each current and selecting the electrode through which the current should flow. or a power converter including a chopper. Figure 2 is a front view showing the arrangement of superconducting coils and electrodes. In Figure 2, a rectangular superconducting coil I, 2.3 forms a triangular ring with one opposing side adjacent to the other. do. A hull 10 is attached to one opposing side 1a of the superconducting coil 1.
The iA. iiA are arranged in parallel in a direction perpendicular to the plane of the paper (see FIG. 3 below). On each of the other opposite sides of the superconductive R coil, electrodes are arranged in parallel and in opposition as shown. In Figure 2, superconducting coils 1, 2.3 are spatially 1
Since they are arranged 20 degrees apart, when a current flows in each superconducting coil in the direction shown, the magnetic field of each superconducting coil is directed outward ζ at right angles to the coil surface, as shown by arrow N.・)
have direction. The magnetic field between adjacent superconducting coils is indicated by arrow S.
It also includes a direction directed inward at right angles to the plane containing the adjacent and opposite sides, as in . Also, since the leakage magnetic flux is created by the vector combination of the magnetomotive force generated by the three superconducting coils 1, 2.3, the strength of the leakage magnetic flux is determined by It reaches zero at the center of the hull 10, is strongest near the surface, and again approaches zero at a distance from the hull 10. FIG. 3 is a developed view showing the arrangement of superconducting coils and electrodes and their effects. In Figure 3, it is clearly shown that each electrode is arranged in parallel and facing each side of the superconducting coil. Regarding superconducting coil 1, electrodes IA, IB and electrode 11A
, 11B, a total of two pairs of electrodes are arranged in parallel along one opposing side. Now, a current is flowing through the superconducting coil 1.2.3 so that a magnetic field is formed inside the superconducting coil from the back side to the front side at right angles to the plane of the paper, and the current is applied to each electrode with the polarity shown in the figure. Assume that current flows between the electrodes in the direction of the solid arrow. Then, for example, between the adjacent opposing sides 1b and 2a of the superconducting coil 1.2, a magnetic field is formed that goes from the front side to the back side at right angles to the plane of the paper. Therefore, according to Fleming's left hand rule, the current flows between electrodes IA and IB and between electrodes 11 and 11.
Seawater between A and 11B generates a water flow in the direction of the double solid line arrow. In addition, the opposite side 1b of the superconducting coil 1.2
, 2a, the same water flow occurs in the direction of the double solid line arrow. L7 Therefore, in this case, the hull is propelled to the right, opposite to the water flow. If the direction of the magnetic field is the same and the direction of the current between each electrode is ζJ, then the direction of the water flow will be to the right, and the ship will be propelled to the left. Incidentally, since the cylinder body 5 in FIG. 1 is made of a magnetically permeable material, it completely suppresses leakage magnetic flux from the superconducting coil 1.2.3 from reaching the outside from the hull. At the same time, it rectifies the water flow and effectively moves the ship forward or backward.In addition, several collars of the annular body consisting of superconducting coils 1, 2, and 3 are moved laterally in Figure 1. The propulsive force is further increased when the superconducting coils and electrodes are arranged side by side in the length direction of the hull 10. Fig. 4 is a partially exploded view showing another effect of the superconducting coils and electrodes. In Fig. 4, the magnetic field is Same as in Fig. 3, between electrodes 11A and IB, and between electrodes 3A and 12B.
When a current is passed in the direction of the solid line arrow at intervals, the direction of the water flow based on the left-hand rule of Fing is diagonally upward to the left, as shown by the double solid line arrow. The two electromagnetic propulsion ships can travel diagonally or turn due to the diagonal water flow. Although detailed illustrations are omitted here,
A plurality of annular bodies consisting of superconducting coils L 2 and 3 are arranged in parallel, and whether or not voltage is applied to each electrode is determined. By appropriately selecting the electrodes, the hull 10 can be operated in various ways. As mentioned above, depending on the strength of the magnetic field generated by the superconducting coil, the magnitude of the current, and the selection of the electrodes through which the current flows, the moon can be easily and freely moved forward, backward, diagonally, or as its speed changes. It is possible to turn left or right, in other words, to select the ship's operating mode.

【Effect of the invention】

Therefore, the present invention has the following superior effects compared to the conventional technology. (1) It is possible to easily and freely select the operating mode of the ship, that is, move 4'B forward or backward or turn left or right as the speed changes. (2) Operation is quiet. (3) Adsorbed surrounding iron-based materials/Q, avoids being attracted to surrounding iron-based structures (3) (4) Since it does not disturb the earth's magnetic field, the ship's presence is undetected. There is no danger, and it is suitable for military ships, especially submarines.
